Description

Technical Field

[0001] The utility model relates to the technical field of plastic masterbatch research and development, in particular to a regeneration device for the research and development of high-temperature protection plastic masterbatch. Background Technique

[0002] Recycling waste plastics into pellets is a recycling method that turns waste plastics into pellets through a pelletizing process. The recycled pellets can be used for molding processing, and the performance of the products obtained is similar to that of the original products, with high economic value. Compared with landfilling and incinerating waste plastics, pelletizing is a real resource recycling and utilization. The regeneration device for plastic masterbatch research and development can melt waste plastics and then extrude and cut them to make plastic masterbatch.

[0003] As an existing public technical solution, the patent publication number CN218227388U discloses an extrusion granulation unit for plastic masterbatch production, including a base, an extrusion granulation machine body, an extrusion mechanism, and a water pumping mechanism. Cold water is pumped out through the water pumping mechanism to cool the material located in the extrusion tube, so as to prevent the still partially soft plastic masterbatch from adhering to the cutting knife during the cutting process by the cutting knife, affecting its next use.

[0004] When the above technical solution is actually implemented, the extrusion granulation machine body melts waste plastics through a heating device. However, due to the simple shell structure of the extrusion granulation machine body, the temperature of the shell of the extrusion granulation machine body is relatively high, which not only easily scalds workers, but also easily dissipates heat. Summary of the Invention

[0005] The purpose of the utility model is to provide a regeneration device for the research and development of high-temperature protection plastic masterbatch, which can insulate the shell of the extrusion granulation machine body to avoid heat dissipation, so as to solve the problems raised in the above background technique.

A support member is arranged on the surface of the rubber and plastic board layer, and a heat insulation layer is fixedly arranged at the end of the support member. An insulation cavity is enclosed between the heat insulation layer and the rubber and plastic board layer. A hot water pipe is fixedly connected to the top of the heat insulation layer and penetrates through the inside of the insulation cavity, the rubber and plastic board layer, and the foam cotton layer. The end of the hot water pipe is communicated with the heating cavity, and the heating cavity is located on the surface of the extrusion tank.

[0008] Preferably, the cooling component includes a cold water pipe fixed above the extrusion pipe, and a water spray head is connected to the output end of the cold water pipe.

[0009] Preferably, the water spray port of the water spray head faces the discharge port of the extrusion pipe.

[0010] Preferably, the cutting component includes a cutting frame fixed on the extrusion tank. A servo motor is arranged on the cutting frame, and the power output end of the servo motor is connected to an adjusting lead screw. The outside of the adjusting lead screw is connected with a cutting blade through a lead screw sleeve.

[0011] Preferably, guide rods are arranged on both the upper and lower sides of the adjusting lead screw, and the guide rods are sleeved with the cutting blade. The cutting blade is perpendicular to the extrusion pipe.

[0012] Preferably, the cutting blade slides on the adjusting lead screw through the lead screw sleeve, and the two cutting blades are symmetrically arranged about the axis of the extrusion pipe.

[0013] Preferably, an extrusion plate is arranged inside the extrusion tank, and the telescopic end of an extrusion cylinder is installed on one side of the extrusion plate. A feed pipe is arranged above the extrusion tank and is communicated with it.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides a technical solution:

[0026] Please refer to Figures 1 to 3 , a regeneration device for the research and development of high-temperature protective plastic masterbatch, including an extrusion tank 1, the output end of the extrusion tank 1 is connected with an extrusion pipe 6, and a cooling component for cooling is arranged above the extrusion pipe 6, cutting components 4 for cutting are arranged on the left and right sides of the extrusion pipe 6, and a heat preservation and protection component 5 for heat preservation is fixedly arranged outside the extrusion tank 1;

[0027] The thermal insulation and protection component 5 includes a heating cavity 501. A foam cotton layer 502 is arranged outside the heating cavity 501, and a rubber and plastic board layer 503 is arranged outside the foam cotton layer 502. A support member 505 is arranged on the surface of the rubber and plastic board layer 503, and a heat insulation layer 506 is fixedly arranged at the end of the support member 505. A heat insulation cavity 504 is formed between the heat insulation layer 506 and the rubber and plastic board layer 503. A hot water pipe 507 is fixedly connected to the top of the heat insulation layer 506, and the hot water pipe 507 penetrates through the inside of the heat insulation cavity 504, the rubber and plastic board layer 503 and the foam cotton layer 502. The end of the hot water pipe 507 is communicated with the heating cavity 501, and the heating cavity 501 is located on the surface of the extrusion tank 1.

[0028] By adopting the above technical solution, hot water enters the inside of the heating cavity 501 through the hot water pipe 507, thereby preventing the temperature inside the extrusion tank 1 from dissipating, and at the same time increasing the surface temperature of the extrusion tank 1. The heating cavity 501 is thermally insulated by the double layers of the foam cotton layer 502 and the rubber and plastic board layer 503 to improve the thermal insulation effect. The heat insulation cavity 504 arranged outside the rubber and plastic board layer 503 can prevent the external low-temperature air from contacting the rubber and plastic board layer 503, and the heat insulation layer 506 outside the heat insulation cavity 504 further increases the heat insulation ability of the thermal insulation and protection component 5 to prevent the temperature of the extrusion tank 1 from dissipating.

[0029] Specifically, as Figure 1 and Figure 4 shown, the cooling component includes a cold water pipe 7 fixed above the extrusion pipe 6, and a water spray head 8 is connected to the output end of the cold water pipe 7. The water spray port of the water spray head 8 faces the discharge port of the extrusion pipe 6;

[0030] The cutting component 4 includes a cutting frame 401 fixed on the extrusion tank 1. A servo motor 402 is arranged on the cutting frame 401. The power output end of the servo motor 402 is connected to an adjusting lead screw 404. The outside of the adjusting lead screw 404 is connected with a cutting blade 405 through a lead screw sleeve. Guide rods 403 are arranged on both the upper and lower sides of the adjusting lead screw 404, and the guide rods 403 are sleeved with the cutting blade 405. The cutting blade 405 is perpendicular to the extrusion pipe 6. The cutting blade 405 slides on the adjusting lead screw 404 through the lead screw sleeve. Two groups of cutting blades 405 are symmetrically arranged about the axis of the extrusion pipe 6;

[0031] An extrusion plate is arranged inside the extrusion tank 1, and the telescopic end of an extrusion cylinder 3 is installed on one side of the extrusion plate. A feed pipe 2 is arranged above the extrusion tank 1 and is communicated.

[0032] By adopting the above technical solution, a melting device is also installed inside the extrusion tank 1 to melt the waste. The waste enters the inside of the extrusion tank 1 through the feed pipe 2. The extrusion cylinder 3 is started, and the extrusion cylinder 3 pushes the extrusion plate to move towards the side close to the extrusion pipe 6, and the molten material is extruded through the extrusion pipe 6. When cutting is required, cold water is sprayed out from the spray head 8 at the end of the cold water pipe 7. An electromagnetic valve is arranged on the cold water pipe 7, and the on-off of the cold water pipe 7 can be controlled through the electromagnetic valve. When it is necessary to cut off the molten material, the servo motor 402 can be started. The servo motor 402 drives the adjusting screw rod 404 to rotate. Thus, the cutting blade 405 is driven to move on the guide rod 403 through the rotating adjusting screw rod 404 and the screw sleeve on the adjusting screw rod 404. After the two groups of cutting blades 405 approach each other, cutting is achieved.

[0033] Working principle: A melting device is also installed inside the extrusion tank 1 to melt the waste. The waste enters the inside of the extrusion tank 1 through the feed pipe 2. The extrusion cylinder 3 is started, and the extrusion cylinder 3 pushes the extrusion plate to move towards the side close to the extrusion pipe 6, and the molten material is extruded through the extrusion pipe 6. When cutting is required, cold water is sprayed out from the spray head 8 at the end of the cold water pipe 7. An electromagnetic valve is arranged on the cold water pipe 7, and the on-off of the cold water pipe 7 can be controlled through the electromagnetic valve. When it is necessary to cut off the molten material, the servo motor 402 can be started. The servo motor 402 drives the adjusting screw rod 404 to rotate. Thus, the cutting blade 405 is driven to move on the guide rod 403 through the rotating adjusting screw rod 404 and the screw sleeve on the adjusting screw rod 404. After the two groups of cutting blades 405 approach each other, cutting is achieved. Hot water enters the inside of the heating cavity 501 through the hot water pipe 507, thereby preventing the temperature inside the extrusion tank 1 from dissipating, and at the same time increasing the surface temperature of the extrusion tank 1. The heating cavity 501 is thermally insulated by a double layer of a foam cotton layer 502 and a rubber and plastic board layer 503 to improve the thermal insulation effect. The heat insulation cavity 504 arranged outside the rubber and plastic board layer 503 can prevent the external low-temperature air from coming into contact with the rubber and plastic board layer 503, and the heat insulation layer 506 outside the heat insulation cavity 504 further increases the heat insulation ability of the thermal insulation protection component 5, preventing the temperature of the extrusion tank 1 from dissipating.

[0034] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
